I find I must concur with HT to an extent here. There is no doubt that the entry of the US into WWII turned the tide, but as I have stated in this very forum a couple of years ago, they didn't do it on their own, and proportionally their losses weren't a patch on the Germans and Japanese.

I will not play the "What if" game, but had the US entered WWII much earlier, say 1939, things would have been very different. Would they have been better or worse? I don't know. Better I hope, but who can tell?

You're only paranoid if you're wrong!
